Product Overview
Allowed discharging
period
The working logic remains the same as for self-use mode. The
difference is:
• In the self-use mode when there is no PV input and the battery
SOC reaches Min SOC
1
(on-grid min SOC), the battery will
enter a dormant state. At this time, if the grid power is lost, the
inverter cannot switch to EPS mode.
• In the backup mode, when there is no PV input and the battery
reaches Min SOC (on-grid min SOC), the inverter enters
standby. At this time, if the grid power is lost , it will switch to
EPS mode until the battery is discharged to the Min SOC
2
(off-
grid min SOC).
Note:
Min SOC
1
(on-grid min SOC): Minimum SOC under grid connection. 30% by default, the
settable range is 30%~100%.
Min SOC
2
(off-grid min SOC): Minimum SOC under off-grid conditions. 10% by default, the
settable range is 10%~100%.
NOTICE!
• You can set two configurable working periods: forced charging period and allowed
discharging period in backup mode. Please refer to "Charge & Discharge Period" for
details.
NOTICE!
• If there is a foreseeable power outage, it is advisable to switch to backup mode in
advance from other modes.
